The 24-item Dysfunctional Attitude Scale (DAS-24) is a short version of the Dysfunctional Attitude Scale, which is a self-report inventory for depressogenic schemata. Objective: 

The object of this study was to examine the reliability and validity of the Japanese version of the DAS-24 (DAS-24-J). Methods: 

Subjects consisted of non-clinical sample 1 (248 university students), non-clinical sample 2 (872 Japanese company employees) and a clinical sample (59 depressed out-patients). Results: 

Internal consistency was satisfactory in all three samples, Cronbach’s α coefficient being higher than 0.85. Test–retest reliability was satisfactory in non-clinical sample 1. The interclass correlation coefficient was 0.79 and there was no significant difference in the average score of DAS-24-J between the two points. The DAS-24-J showed satisfactory concurrent validity with the Japanese Irrational Belief Test-20 (r = 0.76); Automatic Thoughts Questionnaire – Revised total (r = 0.46), negative (r = 0.53) and positive (r =−0.41); and the Beck Depression Inventory-II (r = 0.44 for non-clinical sample, r = 0.63 for clinical sample). The clinical sample showed a significantly higher DAS-24-J score than non-clinical sample 2. According to a factor analysis combining all three samples, three factors were extracted: factor 1 (11 items) corresponded with ‘achievement’ in the original version, factor 2 (6 items) with ‘self-control’ and factor 3 (5 items) with ‘dependency’. Conclusion: 

The DAS-24-J is a reliable and valid instrument to measure depressogenic schemata in Japanese.
